If you are unable to turn off, see this video --> https://www.youtube.com/watch?v=at215z0mUdc
Let me know if you have any difficulty turning it off.
Still doesnt turn off
Go to Settings > Accessbility > TalkBalk and it is set to off there ?
Also, go to Settings > Language & Input > Text to Speech and do you see Driving mode ? If so turn it off.
Then swipe down from the top with two fingers and do you see Car Mode ? If so turn it off.
